IMPROVEMENT IN SEEDING-MACHINES.

Specification forming part of Letters Patent No. 23,558, dated April 12, 1859.

To alt whom it may concern:

Be itknown that I, J. B. DUANE, ofSchenectady, in the county ot' Schenectady and State of New York, have invented a new and Iinproved Broadcast-Seeding Machine; and I do hereby declare that thetollowingis a full, clear,

and exact description of the same, reference 'being had t0 the annexed drawings, makinga vadjustable perforated slide. Fig. 5 is a detached transverse section of the covering device.

Similar letters of reference indicate corresponding parts in the several figures.

standards b, double-edged, or sharp both at their front and back edges, and the teeth or sharesare of triangularorlozengeshape. The

shanks or standards b are fitted into the bars a a either by keys or otherwise, so that they may be readily removed from and fastened thereto, and the teeth reversed, as occasion may require. This will hereinafter be more particularly referred to. The draft-pole C is attached to the bars ce at their center.

D is aseed-box,which extends entirely across the machine and is attached to uprights c c, so that itwill be a shortdistance above theframe A. The bottom d ofthe seed-box is stationary, and has oblong perforations e made in it at equal distances apart, said perforations being almond-shaped, or ot greater width one end than at the other, with rounded or semicircular ends. (See more particularly Fig. 4.)

Directly over or on the perforated bottom dof the seed-box D an adjustable slide,f, is placed. This slidefis perforated with holes g of precisely the same shape as the perforations c. The perforations g, however, are in a reverse position to the perforations e. The

slide f is allowed to he moved or adjusted longitudinally in the seed-box, and is retained at any desired point by a slide, h, at one end of the seed-box, which slide tits into a rack, t', on the slidef. (See Fig. 3.)

In the seed-box D, above the slidef, a recipp rocating bar, E, is placed and fitted in guides or bearingsi t'. The under side of the bar E has pendent rodsj attached to it, which extend downnearly to the slidef. (See Figsl and 3.)

Below the seed-box D a roller, F, is placed. This roller extends the whole length ot' the seed-box, and itis grooved circumferentially, as shown at 7c. The grooves are placed at equal distances apart, and they coincide or register with the perforations c in the bottom d ot' the seed-box, as shown clearly in Fig. 3.

G is an inclined board, which is suspended by chains l below the roller F, and kept at the proper degree of inclination by a chain, l. (See Fig. l.) This board has a. series of pins or rods, m, projecting from its face sides at right angles, said pins or rods being placed in parallel rows, the pins ot' one row being in line with the centers of the spaces between the pins or rods of the adjoining rows.

To the upper or elevated edge'ot' the board G a rod or arm, n, is attached, the upper end of said arm being fitted in an oblong slot, o, in the outer end of a lever, H, which is attached by a fulcrum-pin, p, to the front side ofthe seed-box D. The back end of the lever H is attached to the bar E in consequence ot' being fitted on a vertical pin, q, attached thereto. (See Fig. I.)

In the frame A, and back ofthe seed-box D and inclined board G, two parallel transverse bars, r r, are secured. In these bars are placed inclined rods or teeth s, said teeth inclining backward or toward the back end ot the machine from their upper ends, as shown clearly in Fig. l. There may be one or more rows ot' teeth s in each bari', and the teeth otl one bar may be in line with the centers ot' the spaces between the teeth ot the other. (See Fig. 2.) The bars r may be permanently attached to the frame A, or they may be formed in sections and connected by joints t to the frame, and acted upon by springs u, (see Fig. 5,) in order that the teeth may to a certain extent yield or give as the machine is drawn along.

H is a rollr, which is at the back part of the frame A, and has-its journals tted to the outer ends of' the lower parts ot bent levers I I, which are attached one to each side ofthe frame A by bolts or pins o, said pins passing through the angles of the levers I I. To the upper parts of the levers I I bars J J are attached, one to each, the upper ends of said bars being attached to bars K, the front ends of which are attached to the upper parts of bars L Lthe lower parts of which are secured to the front part of the frame A, one at each side. To the lower parts ofthe bars L L caster-wheels M are attached, one to each, said wheels being attached to projecting ends w of the bars, as shown clearly in Fig. l. The upper ends ot' the bars J J are connected by a traverse-bar, ax, and a chain, bx, is attached to the center of bar d", and 'to a bar, N, which is attached to the bars r r, or to other central parts of the frame. On the bar N a drivers seat, O, is placed, so arranged that it may slide thereon and be adjusted to balance the machine, the adjustment of theseat compensating for the varying weights of different drivers.

P is an oblong box, which is placed in the back part of the frame A, just in front of the roller H. This box has a perforated bottom, and may be divided longitudinally into two or more compartments. One end of the box is supported by a spring, Q, and the opposite end is suspended to a hook, c".

R is a pulley, the axis of which is the bolt or pin that attaches the right-hand lever I to the frame A. This pulley is allowed to rotate freely on its axis, and it is driven bya belt or cord, d", from the roller H, said cord passing around a smaller pulley, e", attached to the outer side otA pulley R, and conce'ntrically with it. The pulley It has pinsfx'projecting horizontally from its face side, and the pulley R, by means of a belt or cord, gx, communicates motion to the roller F, said roller having a pulley, S, on it, one side of which is also provided with horizontal projecting teeth lnx. (See Figs. l and 2.) To the frame A, and opposite one end of the board G, a spring, 12X, is attached. y

The operation is as follows: As the machine is drawn along the teeth B furrow the ground, the teeth (if the ground be light and friable) being adjusted so that the concave edges of the shanks b will face outward, 1f the ground be rather hard and soddy, Ythe teeth are reversed, so that the sods will not be torn up, but divided or out, by the action of the Shanks. The board G is vibrated by the teeth h on the pulley S, said teeth acting against a beveled projection on the board, and the spring i* and the said board, through the medium of the lever H, communicate a vibratory or reciprocating motion to the bar E. The seed in box D is kept in a loose state by the movement of the teethj, and by being agitated by said teeth passes down through the perforations g c ot' the siidefand bottom d into the grooves, the discharge-passages being regulated as regards size by adjusting the slidefof the roller F, said roller throwing the seed on the inclined toothed board G, which distributes the seed eveulyandinabroadcastmanneron theground. The teeth s barrow the seedvinto the ground or cover the same, said teeth being inclined, as previously described, so as to avoid throwing up sods or lumps and to pulverize the latter and to pass over the former. The box P has a reciprocating movement given it by the teeth or pinsf on the pulley R, said pins acting againsta beveled end of the box and the teeth spring Q, and from this box P small seed, grasssecd, or any suitable fertilizer may be distributed, or both may be distributed simultaneously, the seed being in one compartment and the fertilizer in the other. The roller H presses the earth on the seed. The driver from the seat O may elevate the frame A, and consequently the teeth B and s, by drawing down the barsJ J and securing them at the desired point by the chain b", and by fully depressing the bars J J the teeth B s will be elevated entirely free from the ground, so that the implement may be allowed to pass freely over obstructions and also drawn from place to place. This elevating ot' the frame A by the depressing of the bars J J is due to the attachment ot' the roller H to the bars J by the bent levers I I, and to the attachment of the casterwheels M to the projecting ends u of the bars L.

What I claim as new, and desire to secure by Letters Patent, is-

l. The arrangement of the vibratingtoothed board G and agitating-bar E, connected by the lever H,in connection with the adjustable slidej', and perforated bottom d, and grooved roller F, the whole being arranged to operate as and for the purpose set forth.

2. The roller H, when attached to the frame A by the bent levers I I and connected with the casterwheels M through the medium of the bars J J K K L L, arranged substantially as shown, for the purpose set forth.
